Colombia , Tolima, Mariquita. Description of holotype . Male. Length 7.83 mm , width 3.81 mm . Head, pronotum, elytra, venter, and legs dark brown. Head ( Fig. 25 ): surface convex, setose, densely punctate; punctures small (0.16– 0.02 mm ); interocular width 0.7 mm . Eye canthus rounded with sparse, long, slender setae. Frontoclypeal suture well defined, complete. Clypeus parabolic; surface concave, densely punctuate; punctures moderate in size ( 0.022–0.040 mm ) ( Fig. 25 ). Clypeal margin reflexed. Clypeal ventral surface setose, setae slender and long. Labrum reduced, conical, setose; setae moderately long. Labium with poorly developed ligule, prominent. Maxillae with galea poorly developed, lacinia not developed, maxillary palpus with 4 palpomeres; palpomere 4 as long as 1–3 combined. Antennae with 9 antennomeres; antennomere 1 robust; antennomere 2 globose; antennomeres 3 and 4 with base cylindrical, apex broad; antennal club with 4 antennomeres with few setae ( Fig. 25 ). Pronotum ( Fig. 25 ): Convex, wider than long at middle. Surface densely punctate, ocellate, setose; punctures moderate in size ( 0.02–0.05 mm ). Marginal bead present; anterior margin concave, with membrane; lateral margins nearly smooth, setose; setae hair-like, long; posterior margin slightly defined at middle. Anterior angles rounded; posterior angles broadly rounded. Scutellum ( Fig. 25 ): Surface opaque, densely punctate, setose; punctures ocellate, moderate in size ( 0.015–0.025 mm ), center smooth; apex rounded. Elytra ( Fig. 25 ): convex, elongate, subparallel. Surface opaque, densely punctate, setose; punctures moderate in size ( 0.04–0.06 mm ); setae long, hair like. Elytra with 4 striae, interstriae well developed, wide. Elytral margins setose; setae long, hair-like. Hind wings : subcostal and radial veins well sclerotized, not reaching radial sector vein at wing apex; radial sector vein forked at apex; medial vein well developed; medial loop short; cubital vein slightly sclerotized apically from medial loop connection; anal veins 1 and 2 not connected, not forming a basal cell. Venter : prosternal process absent; slightly concave on sides, surface with dense setae; setae slender, short, tawny. Mesosternal surface sparsely setose, slightly concave at middle. Metasternal surface densely punctate, ocellate, setose; setae slender, long; metasternal apex divergent at middle. Abdomen with 3 exposed ventrites medially; ventrite V longer than ventrite IV; prepygidium slightly convex at middle. Pygidium : recumbent; surface densely punctate; punctures ocellate, setose; setae slender, moderately long. Legs : coxae sparsely setose, setae long. Femora with surface sparsely setose, setae long. Protibia with 3 teeth, basal tooth small, dorsal surface with a line of setae from base to apex. Mesotibiae and metatibiae with medial transverse carinae, carinae with 4–5 spine-like setae; apex semicircular, transversely truncate. Tarsal claws bifurcated, symmetrical. Genitalia ( Figs. 26 a-b): parameres simple, symmetrical, elongated, tapered toward apex; parameres shorter than phallobase, with a setose sulcus on outer surface; phallobase slender. Female . Unknown. Distribution . The species is known only from the type locality, which is a tropical dry forest from the inter- Andean valleys of Cordillera Oriental in Mariquita, Tolima, Colombia ( Fig. 29 ). Locality records . ( 1 adult , male). Colombia : Tolima, Mariquita. Temporal distribution . October. Diagnosis . Males of this species are easily distinguished from E. pentaphylla by the following combination of characters: Antennal club with 4 antennomeres, antennomeres 3–5 slender, cylindrical; antennomeres 3 and 4 similar in length, antennomere 5 longer than 3 and 4; elytra with 4 striae, striae widely separated. The unique form of the parameres, which has a sulcus from base to apex on outer margin, is also diagnostic. Etymology . We are pleased to name this species after the senior author’s (JCN) father Pedro Antonio Neita Rodriguez. Natural history . All that is known about the natural history of this species is that the only known specimen was attracted to lights in a dry forest in the Colombian Andes at 380 m ( Fig. 28 ).
